LaCluyze, University of North Carolina at Chapel Hill, on behalf of the CHASE project, report the discovery of an apparent supernova (mag approximately 16.1 +/- 0.2) on an unfiltered image taken on July 10.37 UT with the 0.41-m 'PROMPT 3' telescope located at Cerro Tololo. The new object, which was confirmed at mag approximately 16.0 on July 11.35, is located at R.A. = 3h20m34s.73 +/- 0".1, Decl. = -18°42'54".4 +/- 0".1 (equinox 2000), which is about 8".8 west and 0".8 north of the center of the galaxy NGC 1301. Nothing is visible at this position on archival images taken on Jan. 12.15 (limiting mag 18.5) and June 27.41 (limiting mag 17.5).
